The concept of a pokemon is always evolving. A pokemon is what gamefreak and masuda says is a pokemon. There's a certain quality evident in all pokemon though, it's clear care and thought has been put into them.....even if I'm not personally keen on them. Call me when they reveal a black squiggle pokemon called "aqsprztygapff" and we'll talk about what doesn't seem like a pokemon.

We shouldn't expect to like every pokemon and we should recognise that a pokemon we don't like was just not made to appeal to us. Gamefreak have to try and please everyone with their designs and people's tastes are bound to clash with each other.
